Given a function [latex]f\,(x,\ y)[/latex] and a number [latex]c[/latex] in the range of [latex]f[/latex], a level curve of a function of two variables for the value [latex]c[/latex] is defined to be the set of points satisfying the equation [latex]f\,(x,\ y)=c[/latex].
15.5.4 The Gradient and Level Curves. Theorem 15.11 states that in any direction orthogonal to the gradient. ∇f(a,b) , the function. f. does not change at. (a,b) Recall from Section 15.1 that the curve. f(x,y)=.
Jan 22, 2022 · I am supposed to find and draw a few level curves for the function $g(x,y) = e^{\sqrt{x^2-y^2}}$. I have already calculated the domain of the function: $Df=\lbrace(x,y) : y ≤ ±|x|\rbrace$ In order to find a few level curves, I began by calculating the following for a constant c: $e^{\sqrt{x^2-y^2}}=c$ , This gives $\sqrt{x^2-y^2}=\ln(c)$ and ...
Sep 29, 2023 · A level curve of a function \(f\) of two independent variables \(x\) and \(y\) is a curve of the form \(k = f(x,y)\text{,}\) where \(k\) is a constant. A level curve describes the set of inputs that lead to a specific output of the function.
Jan 28, 2022 · Another good way to visualize the behaviour of a function \(f(x,y)\) is to sketch what are called its level curves. By definition, a level curve of \(f(x,y)\) is a curve whose equation is \(f(x,y)=C\text{,}\) for some constant \(C\text{.}\)
The level curves of a function z = (x, y) are curves in the x y -plane on which the function has the same value, i.e. on which , z = k, where k is some constant. 🔗. Note: Each point in the domain of the function lies on exactly one level curve.

The level curves are given by $x^2-y^2=c$. For $c=0$, we have $x^2=y^2$; that is, $y=\pm x$, two straight lines through the origin. For $c=1$, the level curve is $x^2-y^2=1$, which is a hyperbola passing vertically through the $x$-axis at the points $(\pm 1,0)$.
